Hi and welcome
Thanks for posting the photos.
Most 7-up bottles are green so your amber bottle which is incidentally marked 7-UP TEXAS CORP. HOUSTON TEXAS is an earlier bottle which fairly scarce.
They command $75-125 in the current market.
Condition is really really important. Minor details matter. Chips, wear, bruises, tiny areas of missing or worn paint on the ACL label all detract from value.
I would say selling on ebay is about as good a place as anywhere. Be sure to post really clear photos which show all the details of the glass surface.
